Function in test mode
Explanation
Pressing this key when the focus servo and spindle servo
are operating correctly in closed loops puts the tracking
servo into a closed loop, displays the track number being
played back and the elapsed time on the front panel, and
outputs the playback signal.
If the elapsed time is not displayed or not counted cor-
rectly or the audio is not played back correctly, it may be
that the laser is shining on the section with no sound re-
corded at the outer edge of the disc, that something is out
of adjustment, or that there is some other problem.
This key is a toggle key.
Pressing this key when the
tracking servo is closed opens it and pressing this key
when the tracking servo is open closes it. This key has no
effect if no disc is mounted.
